I am trying out PVC but I can't seem to get good results. When I use PVC I get a nice looking image of my Beagle. But when I send it to my CNC I get very bad results. As seen in the pictures. I can't even tell what it is I just machined out.

The 3rd picture is What I would like to do. Except put the image of the dog in place of the fish. Am I doing something wrong or is PVC not the right software? If PVC is not the right software, can you recommend the right software?

I use a Carving Max Depth of .05 and a line spacing of 110%. The attached picture was done with a 45 degree V bit.

You need to apply a sealer to the image, and then fill the carved lines with paint. I use black acrylic. Wipe off the excess with a damp cloth. After the paint dries, sand off any excess that is left on the surface. The image will pop out.
